Abstract

The relative error of the magnetic induction intensity caused by the magnetic field excitation device of multiple air-core coils is caused by the position error during the assembly process. The error of temperature measured by the magnetic nanoparticles thermometer (MNPT) increases significantly when the error of excited magnetic fields is greater than 0.1%. The theoretical model of the position error for the air-core coil is constructed based on the Biot-Savart law. The simulation results show that the relative error of the magnetic induction intensity in the assembly process of a single air-core coil can be reduced by adding compensation coils, so that the minimum error is less than 0.1%. This method is also applicable to multiple air-core coils. Moreover, we also obtained the minimum error transfer route during the construction of multiple air-core coils. It is expected to provide an effective solution for reducing the temperature error of MNPT caused by the assembly process of multiple air-core coils.
